[PATCH for-rc 4/7] IB/hfi1: Return correct value in general interrupt handler

[Dennis Dalessandro <dennis.dalessandro@xxxxxxxxx>]

From: Kamenee Arumugam <kamenee.arumugam@xxxxxxxxx>

The general interrupt handler returns IRQ_HANDLED whether an IRQ
was handled or not.
Determine if an IRQ was handled and return the correct value.
